Prominent KGI Securities analyst Ming-Chi Kuo is back once again with yet more iPhone 8 predictions, this time professing that Apple’s next-generation smartphone will adopt a stacked logic board setup in order to maximize the battery life provided to users.
From an aesthetic design perspective, this shouldn’t really change much, but it will potentially result in the 4.7-inch iPhone 8 having comparable (or even more) battery life to Apple’s current 5.5-inch iPhone 7 Plus flagship. This – if true – will be a huge jump from what Apple has been providing us with thus far.
The KGI Securities analyst has a particularly impressive record of predicting Apple’s future plans, both in terms of updated product design and new product releases.
If the next-generation iPhone indeed comes packed with the said stacked logic board, it will result in a device featuring OLED display and a battery capacity comparable to that of 5.5-inch iPhone 7 Plus – all packed in a form factor which is similar in physical size to the current 4.7-inch iPhone 7. As for actual capacity of battery, Kuo predicts that the 4.7-inch iPhone 8 model will ship with an L-shaped two-cell battery boasting a 2,700mAh cell:
As battery material tech isn’t likely to see major breakthroughs in the next 3-5 years, mainboard area can only be reduced via stacked SLP, which makes space for larger battery and extended usage time. Thanks to stacked SLP, we expect the OLED iPhone to have similar dimensions to a 4.7” TFT-LCD iPhone, and have comparable battery capacity (equipped with around 2,700 mAh L-shaped 2-cell battery pack) to a 5.5” TFT-LCD iPhone. The battery life of the OLED iPhone could be better than that of the 5.5” TFT-LCD model as OLED panels are more energy-efficient than their TFT-LCD counterparts.
One of the things to take into consideration here is that an OLED display is actually a lot more power-efficient, and therefore battery friendly, compared to a device with an LCD display such as all the iPhone models to date. That in itself could mean that Apple’s 4.7-inch iPhone 8, with its new internal design and logic board, could provide a battery performance that goes well above and beyond what is currently being experienced with the larger iPhone 7 Plus model. That device currently has a 2,900mAh cell integrated into it, but it could be outperformed with the new technical DNA of the next-generation iPhone.
We’re sure that more will come into the public domain about this as time progresses, but for now, as things stand, all of the speculation points to an extremely impressive iPhone 8.
